When trying to view an ArcIMS Web site in a browser, an "ImageRetrievalException" error message is returned.
The Website and Output directories are in a location other than the Web server root directory.
During ArcIMS installation, if a location for the Website and Output directories other than the Web server root directory was selected, virtual directories for Website and Output must be created.
Steps for doing this vary according to the Web server and servlet engine being used. See the Web server documentation or the ArcIMS Installation Guide for instructions on creating these virtual directories.
